Definitions
- Example embodiments relate to systems and methods for delivering discrete amounts of particulate material during high speed manufacturing of particulate bearing articles of manufacture. At least one example embodiment relates to systems and methods for repetitively delivering discrete amounts of particulate additives to cigarette filter tow material.
- Articles of manufacture such as particle bearing cigarette filters, individual- sized packets of granular food products or condiments, capsuled pharmaceuticals, ammunition and the like may require repetitive placement of precisely metered charges of particulate matter at some location along the production-line procession of the articles. Difficulties may arise in pursuing sufficient speed in the mass production of such articles without sacrificing consistency, damaging the material and/ or exacerbating spillage, particularly at elevated manufacturing speeds where ricochet and vibration may impair process control and consistency.
- process control may suffer at high machine speeds from inconsistent metering and pulverization of the material, particularly in those prior machines where fast moving machine components are allowed to impinge stationary or relatively slow moving particulate material.
- certain prior particle metering devices contain a supply of particle in a hopper and allow the rim of a rotating metering wheel to rotate through the relatively stationary collection of particles. Such an arrangement creates a pulverizing action upon the particles which generally increases with machine speed.
- Filter rods have been produced having particles distributed uniformly throughout the filter rod. With such filter rods, particles are cut as the rod is converted into segments, thereby dulling the knife and producing particle dust and scatter. Further, rods which continuously distribute particles require a secondary combining operation to produce a final filter with a mouthpiece segment void of particles.
- a plug-space-plug method of producing filters, wherein particles are inserted into spaces between plugs, has been employed. However, this method may require the expense of a combined filter, where the carbon-on-tow filter is combined with a mono mouthpiece.
- At least one example embodiment relates to a system for manufacturing a filter.
- the system may further include a closing unit disposed downstream of the particle distribution apparatus for closing the particle-bearing stream of filamentary material so as to capture groupings of particle material at discrete locations within a closed rod of filamentary material.
- the system may further include a cutter disposed downstream of the closing unit for cutting the closed rod into discrete filter plugs or 2-up pairs of filter plugs.
- the fluid may be a plasticizer, and the particle material distributed onto the wet continuous stream of filamentary material may be at least partially adhered to the continuous stream of filamentary material by the plasticizer.
- the support structure may be a solid, planar support structure.
- the continuous stream of filamentary material below the particle distribution apparatus may have a planar, ribbon-like shape.
- the particle material may comprise rupturable beads.
- the particle material may comprise carbon granules.
- the apertured distribution belt may be advanced at the same speed as the continuous stream of filamentary material.
- a bottom of the apertured distribution belt may be mounted at a distance from the support structure such that a particle accumulation space is provided between the particle distribution apparatus and the continuous stream of filamentary material.
- At least one example embodiment relates to a method for manufacturing a filter.
- the particle-bearing stream of filamentary material may contain discrete spaced-apart groupings of the particle material.
- the method may further include closing the particle-bearing stream of filamentary material so as to capture groupings of particle material at discrete locations within a closed rod of filamentary material.
- the method may further include cutting the closed rod into discrete filter plugs or 2-up pairs of filter plugs.
- the method may further include applying fluid to the continuous stream of filamentary material upstream of the particle distribution apparatus, such that that particle material is distributed onto a wet continuous stream of filamentary material.
- the method may further include applying a plasticizer as the fluid, such that the particle material distributed onto the wet continuous stream of filamentary material is at least partially adhered to the continuous stream of filamentary material by the plasticizer.
- the method may further include advancing the continuous stream of filamentary material along a solid, planar support structure as the support structure.
- the method may further include distributing the particle material onto the continuous stream of filamentary material having a planar, ribbon-like shape.
- the method may further include distributing the particle material having rupturable beads.
- the method may further include distributing the particle material having carbon granules.
- the method may further include advancing the aperture distribution belt at a same speed as the continuous stream of filamentary material.
- the method may further include distributing particle material through the spaced openings in the apertured distribution belt which is mounted at a distance from the support structure such that the particle material crosses a particle accumulation space provided between the particle distribution apparatus and the continuous stream of filamentary material after passing through the spaced openings.
- FIG. 1 is a schematic side view of a filter rod maker system constructed in accordance with at least one example embodiment
- FIG. 2 is a partial side view of a granular inserter utilized in accordance with at least one example embodiment
- FIG. 5 is a cross-sectional as viewed from line V— V in FIG. 4 according to at least one example embodiment.
- FIG. 6 is a filter cigarette constructed in accordance with at least one example embodiment. DETAILED DESCRIPTION
- spatially relative terms such as “beneath”, “below”, “lower”, “above”, “upper”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
- Example embodiments are described herein with reference to cross- section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures). As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/ or tolerances, are to be expected. Thus, these example embodiments should not be construed as limited to the particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of this disclosure.
- the plasticizer applied by the plasticizer applicator 28 may be a softening agent that is added in small quantities to the cellular acetate tow to tack the fibers together at points where the filaments cross one another.
- plasticizers include, but are not limited to, triacetin (also known as glycerol triacetate, or PZ), trimethylene glycol diacetate (also known as TEGDA), and mixtures thereof.
- a plasticizer applicator 28 is located upstream of particle distribution apparatus 40, such that the filamentary material 22 is tacky with plasticizer applied by the plasticizer applicator 28 as it moves beneath the particle distribution apparatus 40.
- a cigarette 86 includes a wrapped tobacco rod 88, which is attached by a tipping paper 90 to an individual filter plug 80 having a single charge of metered particle material 82 within it and including folded portions of fibrous material 84 adjacent thereto.
- a mouthpiece filter (not shown) may be provided at a free end portion 94 of filter plug 80.
